Serpierite with Ktenasite
stock #8 GRC-1006
Kamereza Mines, Aglos Konstantinos
Attiki Prefecture Laurion District, Greece
10.7 x 7 CM (cabinet)
price: $200


A bright, sparkling and very 3 dimensional piece of these two rare minerals from the classic locality of Laurion. Excellent coverage and color. Serpierite is a sky blue hydrated sulfate and the mid member of the Deviline and Rapidcreekite series. It is nice to have a rare mineral that is also cabinet sized and pretty since this is usually available just as micro specimens!
Bournonite cogswheel
stock #6.2-891
Yaogangxian Mine, Yizhang County
Hunan Province, China
3.4 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $400


We have all seen a lot of Bournonite from Yaoganxian, some is world class, but most has a lot of serious damage. Clean examples of this brittle mineralare quite rare, and to find a nearly pristine "cogswheel" type that is crystalized all around (floater) is very special. This complex cluster has excellent mirror bright metallic luster, great form and esthetics. Very careful examination shows a few hard to find chips all under 1 mm in size, not distracting at all. For some reason, there have been more single, prismatic type crystals from Yaogangxian, this example looks much more English than Chinese! Super reasonable !
